Description
This analysis searches for jet-quenching effects in OO collisions at $\sqrt{s_{\mathrm{NN}}}=5.36$ TeV using semi-inclusive hadron-jet correlations. Event activity (EA) is characterised primarily by FT0, while ZDC observables are used to test whether the EA selection retains sensitivity to collision geometry. A clear non-linear correlation between FT0 and ZDC signals indicates that FT0-based EA preserves a strong geometric component.
The main observable is the recoil-jet distribution measured relative to a high-$p_{\mathrm{T}}$ charged trigger hadron as a function of EA. The semi-inclusive approach is insensitive to CNM effects and centrality bias, providing a cleaner probe of possible parton energy loss in the OO system. Within the current sensitivity, no significant variation of the recoil-jet spectrum with EA is observed.
